What Happens When a Firm Adopts Lean Manufacturing?

Posted by seoexpert131 on June 4th, 2023

Firms embracing lean manufacturing embrace its continuous improvement principle, meaning their employees are constantly seeking ways to optimize processes.

These improvements reduce cycle times and production efficiency, leading to decreased operational costs and thus increased profits as well as higher employee morale.

Identifying Value

At the core of lean manufacturing lies identifying customer value. This involves using customer perspective as a guide and eliminating processes or steps that don't add anything of benefit. Eliminating waste can save both time and money for any organization - it reduces stockpiling inventory costs while simultaneously producing just-in-time production which further lowers storage fees while simultaneously decreasing risk associated with defective products or rework costs.

The second step in mapping the value stream is creating a flow diagram. This can help identify areas of waste or inefficiency that require improvement, as well as help determine optimal layout of assembly lines and machine equipment, plus any areas where additional employees may be needed to streamline production. It is vital that employees become involved with this process of mapping value streams and identifying waste as this requires major cultural shifts.

Mapping the Value Stream

Value stream mapping involves recording and analyzing the current production process to identify waste. It begins at product delivery time and works backwards to isolate production steps which could be eliminated, along with ways to enhance them further. Value chain analysis helps pinpoint ways of improving each step along its value chain; such as inventory overproduction, transporting materials between warehouse and delivery point, rework motion defects. A3 thinking helps identify countermeasures against such problems.

Lean manufacturing includes creating a pull system in which production only occurs on demand from customers, thereby decreasing stock levels and providing for more regular delivery. A steady flow in production can motivate employees and reduce raw material, labor and energy costs as well as harmful pollutants generated. Timelines and travel distances recorded at the bottom of maps provide further details regarding cycle times and work content in processes.

Eliminating Waste

To effectively eliminate waste, employees must have a firm grasp on what customers value and be given opportunities to improve processes or systems using Kaizen as an approach.

This approach typically involves employees making incremental improvements that reduce production lead times and boost overall system efficiencies, helping companies reduce costs without incurring the costs or risks associated with major system-wide overhauls.

Lean manufacturing techniques focus on eliminating waste, or "muda" in Japanese, from production. This includes activities that don't add value or support work that doesn't add value (muda). Manufacturers can eliminate such waste through production control systems like Takt Time and Kanban.

They can further minimize waste by employing Just-In-Time and Flow manufacturing techniques to cut back production delays by eliminating buffers; producing exactly what customers require when needed and thus cutting down inventory costs and storage fees.

Creating Flow

Lean Manufacturing Principle IV involves developing an uninterrupted manufacturing process. To accomplish this goal, companies must remove functional barriers and set up production systems based on customer demand rather than internal schedules; this enables inventory levels to decrease while products are produced when needed.

Implement a just-in-time production process. Kanban systems should be used to indicate when additional work is necessary; employees should spend as little time traveling between work areas as possible (Value Stream Mapping); workers are able to complete their jobs uninterrupted (Flow), and tools like Poka-Yoke and Jidoka are employed to prevent human errors during production.

MicroMetl, a manufacturer of heating and air conditioning equipment, implemented lean principles when its employees discovered they were walking 1.5 miles around its factory to complete assembly tasks. By employing lean improvements, this distance had been cut by half to 100 feet.
